Aliens from 1004 star systems may know about Earth’s habitability

Unfortunately, the hunt for extraterrestrial life has not yet borne fruit, but fortunately, the responsibility for the first contact may not lie with us.

(ORDO NEWS) — New research shows that more than 1,000 nearby star systems have a direct view of Earth, which would allow hypothetical alien astronomers to detect us and likely try to contact us.

Many of the same tricks that Earth scientists use when trying to find “brothers in mind” can also be used by alien astronomers to find us.

According to a study published Tuesday in the Royal Astronomical Society’s Monthly Notices, 1004 star systems (95% of which are old enough to support hypothetical life) are within 300 light-years of Earth and provide their exoplanets with a clear view of Earth.

In fact, more than 500 exoplanets could observe Earth for 10 hours a day if our Sun did not obstruct the view.

In the same way that Earth astronomers learn details about exoplanets by observing them as they pass between us and their stars, hypothetical alien scientists can gather information about Earth. They may already know that the Earth is a rocky planet with a hospitable atmosphere.

“If aliens were searching, they would see signs of the biosphere in the atmosphere of our pale blue dot,” lead author and Cornell University astronomer Lisa Kaltenegger said in a press release.
